Government of Canada in the context of "Lieutenant governor (Canada)"

Canada has ten provinces and three territories that are sub-national administrative divisions under the jurisdiction of the Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the world's second-largest country by area.

The major difference between a Canadian province and a territory is that provinces receive their power and authority from the Constitution Act, 1867 (formerly called the British North America Act, 1867). Territories are federal territories whose territorial governments have powers delegated to them by the Parliament of Canada. Powers are divided between the Government of Canada (the federal government) and the provincial governments by the Constitution Act, either exclusively or concurrently. A change to the division of powers between the federal government and the provinces requires a constitutional amendment. A similar change affecting the territories can be performed unilaterally by the government or Parliament of Canada.

The Constitution Act, 1867 (French: Loi constitutionnelle de 1867), originally enacted as the British North America Act, 1867 (BNA Act), is a major part of the Constitution of Canada. The act created Canada, a federal country, and defines much of its structure, including the Parliament of Canada (composed of the monarch, the House of Commons, and the Senate), the executive, parts of the court system, and the division of powers between the federal government and the provinces. The act also created two new provinces, Ontario and Quebec, and set out their constitutions.

In 1982, with the patriation of the Constitution, the British North America Acts which were originally enacted by the British Parliament, including this act, were renamed the Constitution Acts. However, the acts are still known by their original names in records of the United Kingdom. Amendments were also made at this time: section 92A was added, giving provinces greater control over non-renewable natural resources.

The court system of Canada is made up of many courts differing in levels of legal superiority and separated by jurisdiction. In the courts, the judiciary interpret and apply the law of Canada. Some of the courts are federal in nature, while others are provincial or territorial.

The Constitution of Canada gives the federal Parliament of Canada exclusive jurisdiction in criminal law, while the provinces have exclusive control over much of civil law. Each province has authority over the administration of justice within that province.

Ottawa is the capital city of Canada. It is located in the southern portion of the province of Ontario, at the confluence of the Ottawa River and the Rideau River. Ottawa borders Gatineau, Quebec, and forms the core of the Ottawa–Gatineau census metropolitan area (CMA) and the National Capital Region (NCR). As of 2021, Ottawa had a city population of 1,017,449 and a metropolitan population of 1,488,307, making it the fourth-largest city and fourth-largest metropolitan area in Canada.

Ottawa is the political centre of Canada and the headquarters of the federal government. The city houses numerous foreign embassies, key buildings, organizations, and institutions of Canada's government; these include the Parliament of Canada, the Supreme Court, the residence of Canada's viceroy, and the Office of the Prime Minister.

The Numbered Treaties (or Post-Confederation Treaties) are a series of eleven treaties signed between the First Nations, one of three groups of Indigenous Peoples in Canada, and the reigning monarch of Canada (Victoria, Edward VII or George V) from 1871 to 1921. These agreements were created to allow the Government of Canada to pursue settlement and resource extraction in the affected regions, which includes the entirety of modern-day Alberta, Manitoba, and Saskatchewan, as well as parts of modern-day British Columbia, Ontario, the Northwest Territories, Nunavut, and Yukon. These treaties expanded the Dominion of Canada resulting in the displacement of Indigenous populations for large tracts of land in exchange for promises made to the indigenous people of the area. These terms were dependent on individual negotiations and so specific terms differed with each treaty.

These treaties came in two waves—Numbers 1 through 7 from 1871 to 1877 and Numbers 8 through 11 from 1899 to 1921. In the first wave, the treaties were key in advancing European settlement across the Prairie regions as well as the development of the Canadian Pacific Railway. In the second wave, resource extraction was the main motive for government officials. During this time, Canada introduced the Indian Act extending its control over the First Nations to education, government and legal rights. The federal government did provide emergency relief, on condition of the Indigenous peoples moving to the Indian reserve.

The Saguenay–St. Lawrence Marine Park is a National Marine Conservation Area, one of three in the Canadian national park system, located where the Saguenay River meets the maritime estuary of the St. Lawrence River. This park is jointly managed by Parks Canada (Government of Canada) and Sépaq (Government of Quebec). It is the first park in all of Canada to protect a purely marine environment, and covers a surface area of 1,245 km. The area that is now the Saguenay–St. Lawrence Marine Park is a part of the Innue Essipit First Nation's land claim, and a treaty resulting from this claim could impact activities that are practiced within the park. The region surrounding the park is an important part of the history of Canada, being one of the first points of contact between Indigenous Peoples and European explorers and the birthplace of the intercontinental fur trade.

The Maritime estuary of St. Lawrence begin at the Saguenay Fjord this meeting form a distinct ecosystem for the species in the park. Different species of whales in particular are drawn to the rich food supply stirred up by the mixing of these waters. One of these species is the St. Lawrence Beluga whale, which is endemic to Canada and a species at risk. The most popular activity in the park is whale-watching. The park provides a variety of opportunities on and off the water for visitors to see them. There are several human impacts that threaten the park such as climate change, noise pollution, chemical pollution, and overfishing, many of which are not fully understood.

Inuit (singular: Inuk) are a group of culturally and historically similar Indigenous peoples traditionally inhabiting the Arctic and Subarctic regions of North America and Russia, including Greenland, Labrador, Quebec, Nunavut, the Northwest Territories, Yukon (traditionally), Alaska, and the Chukotsky District of Chukotka Autonomous Okrug. The Inuit languages are part of the Eskaleut languages, also known as Inuit-Yupik-Unangan, and also as Eskimo–Aleut.

Canadian Inuit live throughout most of Northern Canada in the territory of Nunavut, Nunavik in the northern third of Quebec, the Nunatsiavut in Labrador, and in various parts of the Northwest Territories and Yukon (traditionally), particularly around the Arctic Ocean, in the Inuvialuit Settlement Region. These areas are known, by Inuit Tapiriit Kanatami and the Government of Canada, as Inuit Nunangat. In Canada, sections 25 and 35 of the Constitution Act of 1982 classify Inuit as a distinctive group of Aboriginal Canadians who are not included under either the First Nations or the Métis.

Canadian federalism (French: fédéralisme canadien) involves the current nature and historical development of the federal system in Canada.

Canada is a federation with eleven components: the national Government of Canada and ten provincial governments. All eleven governments derive their authority from the Constitution of Canada. There are also three territorial governments in the far north, which exercise powers delegated by the federal parliament, and municipal governments which exercise powers delegated by the province or territory. Each jurisdiction is generally independent from the others in its realm of legislative authority. The division of powers between the federal government and the provincial governments is based on the principle of exhaustive distribution: all legal issues are assigned to either the federal Parliament or the provincial Legislatures.
